SAVANTEC diamond burnishing tool can be used to roll the outer circle, inner hole (greater than a certain diameter), end face, etc. on the lathe. It is not limited by the diameter except the inner hole, and has wide applicability.

Under the microscope, during the cutting process of the workpiece, the tool tip will leave a step like cutting trace on the surface. The diamond will overcome the yield point of the material during the sliding process on the workpiece surface under the effect of the spring force, causing plastic deformation on the material surface, forcing the highest point of the cutting trace to flow into the lowest point, so as to obtain a smooth and flat mirror. In the process of rolling, the material will be hardened due to plastic deformation, thus improving the fatigue strength of the workpiece surface.
To achieve the best squeezing effect, the surface finish of the last cutting process of the workpiece should be within RZ15um. Refer to the right figure
